我们研究一个通用的易货市场，每个代理商都有几种不可分割的物品和希望交流的希望。没有像钱这样的交换媒介。代理商对感兴趣的物品有一般的喜好，并可能会获取几个项目。我们提出了一种称为马尔可夫核心的实用且明智的解决方案，从而推广了核心的经典概念。马尔可夫核心分配是单独的，帕累托效率的，并且通过与当前的任务相比而不是其初始捐赠，对任何联盟偏差都具有稳定性，并且被证明是分散市场过程的自然结果。
We study a general barter market where every agent is endowed with several heterogeneous indivisible items and wishes to exchange. There is no medium of exchange like money. Agents have general preferences over their interested bundles of items and may acquire several items. We propose a practical and sensible solution called a Markovian core, generalizing the classical notion of the core. A Markovian core allocation is individually rational, Pareto-efficient, and stable against any coalition deviation by comparison with their current assignments instead of their initial endowments and is shown to be a natural outcome of a decentralized market process.
